Question | Answer |
---|---|

Standard Notation | Just the number as we normally write it. |

Equivalent | Equal in value but in different forms. |

Whole Numbers | The number (0,1,2,3,....). There is no fractional or decimal part and no negatives. |

Expanded Notation | Writing a number to show the value of each digit. It is shown as a sum of each digit multiplied by its matching place value (units, tens, hundreds, etc.) |

Exponential Notation | A shorthand way of representing repeated multiplication of the same factor. |

Scientific Notation | Where a number is written in two parts: First: just the digits (with the decimal point placed after the first digit), Followed by: x10 to a power that would put the decimal point back where it should be. |

Integer | A number with no fractional part. For example, -2, -1, 0, 1, 2 |

Prime Factorization | A number, expressed as a product of prime factors. For example, of 24 is 2 x 2 x 2x 3. |

Decimal | A fraction that that has a denominator of a power of ten, the power depending on or deciding the decimal place. |

Positive Number | Numbers greater than 0 that can be written as a fraction or a terminating or repeating decimal. |

Negative Number | A number less than 0; a number to the left of zero on the horizontal number line. |

Array | A rectangular arrangement of objects in rows and columns. |

Fractions | A number in the form a-b or a/b, where a and b are whole numbers and b is not 0. They are used to name part of a whole object or a part of a whole collection of objects, or to compare two quantities. They can also represent division. |

Percents | Per hundred, or out of a hundred. For example "48% the students in the school are boys" that means that out of 100 students in the school, 48 are boys. |

Common Denominator | Two fractions is any nonzero number that is a multiple of the denominators of both fractions. |

Sum | The answer in an addition problem. |

Least Common Denominator | The least common multiple of the denominators of every fraction in a given set. |

Place Value | Determines the value of a digit in a number, written in standard notation, as determined by its position. Each place has a value ten times that of the place to its right and one-tenth the value of the place to its left. |

Simplest Form | A fraction in which the numerator and denominator have no common factor except 1 and the numerator is less than the denominator. |

Difference | The answer in a division problem. |

Numerator | In a whole divided into a number of equal parts, the number of equal parts being considered or discussed. The number or variable on the top of the fraction. |

Equivalent Fractions | Fractions that have different numerators and denominators but name the same value or number. |

Denominator | The number of equal parts into which the whole (or ONE or unit) is divided. The number or variable on the bottom of the fraction. |

Greatest Common Factor | The highest number that divides exactly into two or more numbers. |

Least Common Multiple | The smallest number that is a multiple of two or more numbers. |

Multiple | The result of multiplying by a whole number. For example 20 is a multiple of 4 and 5. |

Exponent | A symbol or number placed above and after another symbol or number to denote the power to which the latter is to be raised. |

Absolute Value | The absolute value of a positive number is the number itself. |

Compatible Numbers | Numbers that are close in value to the actual numbers and easy to add, subtract, multiply, or divide mentally. |

Front-End Estimation | Estimating to the highest place value. Ex. 7,438=7,000. |

Round | This means reducing the digits in a number while trying to keep it's value similiar. |

Prime Number | This is a number that can be divided evenly by only 1 or itself. It must be greater than one. |

Estimate | A calculation of a close, rather than exact, answer; a "ballpark" answer; a number close to another number. |

Composite Number | This is a number that can be divided evenly by numbers other than one or itself. It has more than one factor pair. |

Factor | Factors are the numbers you multiply together to get another number. For example: 3 and 4 are factors of 12 because 3x4=12. |
